  • Patent number: 7571839
    Abstract: The present invention relates to a load bearing apparatus, and more particularly, to a passive exoskeleton whereby a load may be placed on the passive exoskeleton and thereby transfer weight of the load from the passive exoskeleton to a ground surface. The passive exoskeleton comprises a rigid body member for attaching proximate a portion of a user's body, a sliding rod attached with the body member, and a ground surface engage-able foot analog attached with the sliding rod. When a user places a load on the body member, weight of the load from is transferred from the body member, through the sliding rod, and into the foot analog, causing the passive exoskeleton to support at least a portion of the load.

  • Patent number: 7445138
    Abstract: A load bearing apparatus is presented in the form of a passive exoskeleton whereby a load may be placed on the passive exoskeleton and thereby weight of the load from the passive exoskeleton is transferred to a ground surface. The passive exoskeleton is made of a rigid body member for attaching proximate a portion of a user's body; a sliding rod attached with the body member; a ground surface engage-able foot analog attached with the sliding rod; a rocker pivotally attached with the body member; a load pin attached with the sliding rod and operably attached with the rocker; and a bias block attached with the body member for engaging with the rocker. As a user walks, the bias block pivots the rocker to aid the load pin in transferring weight to the rocker and thereafter through the sliding rod to the foot analog and ground surface.
